. FACING TOOL.

Application filed November 9, 1921. seriaiuo. 514,110.

Facing Tools, of which the following is a specification.

My invention relates to improvements in facing-tools, and the object of my improvement is to. supply-a tool of this class manually operable, and of a convenient andsimple design suitable for facing. certain bearingend faces of front aXle-yokes and spindle body bushings such as are used in motorcars, or for operating on any otherdevmes to which the tool may be applicable.

I have accomplished the above object by the means which are hereinafter described and claimed, and which areillustrated 1n the accompanying drawings, in which Fig. 1 is an elevation of said tool with an element thereof in partial section, as employed to face the lower bearing-end of the upper member of an axle-yoke and Fig. 2 is another elevation ofthe tool with itselements rearranged and employed to face the outer end of a spindle-body bushing. Flg. 3 1s a plan of one end of the cutter-head of sald tool, and Fig. 1 is a plan of a washer used in connection with the tool.

In said drawings, similar numerals of reference denote similar parts throughout the several views.

My improved facing-tool comprises but few'coacting elements. The numeral 1 denotes a cylindric bolt-shaped shaft having a squared head 2-and having its opposite end exteriorly threaded at 4, and having a key seat 23 throughout the length of the thread on its longitudinal axis. The shaft 1 has a pair of longitudinally spaced cylin dric transverse orifices 8 near the head 2.

The numeral 8 denotes a hollow cylindri single cutting blade 18, but it is apparent that a cutter head may be used having one or more cutting edges, either integral or de tachable. The shoulder 10 as also the tool 13 have alined orifices 11- to receive the securing screws 12.

The numeral 5 denotes a body having one end part squared with an. end socket 7 in-- teriorlythreaded, the other and diminished end being exteriorily threaded at 6.

The numeral-16 in 4 denotes a washer having an integral tongue 24 projecting in wardly,;of suitable width and length to en- 7 I gage thekey seat '23 at the lower threaded end a of. the shaft 1...;It is understood that the inside vdiameter of the washer 16 is such that itslides readily-onthe; threaded end I 1 of the shaft 1 and islprevented from turn mg by the engagement of the tongue 24 in the key-way 23.. I

use in facing work on the yokes and the spindle-body bushings of a 'wellsknowntype of car, but of course, is not restricted thereto, as 1t 1s adaptable to any aXle yoke and spindle body of similar design. V

InFig. 1 is shown an end part of a front, axle 17 having an' integral terminal yoke, j vertically spaced and whose fork extremities are cylindrically vertically orificed in aline-' As the shaft 1 of the tool is of like dimensions to such a spindle-bolt, it may be passed through said alined orifices as also through e .ment to receive a spindle-bolt, not shown.

lower threaded end 1- of the said shaft 1 is 7 adjustably supported on the ;bossed extremity 6 of the body 5, as the part 6 ismeshed with the threads-in the lower yoke bearing.

As the upper bearing face 18 mentioned is that which sustains-the wear of use, this is the one which requires facing accurately to be kept smooth and free'from irregularities. The tool is operated manually by the application of a wrench or handle to its head 2 to' rotate it, while the cutter head 8 is forced be faced by thepressure on the lower'end of the shaft 1, bymeans of manually turn against the surface to y 75" The tool is particularly well adapted for ing. 7

ing the body 5, with the extremity 6 located in the threaded end of the lower yoke bear- Referring now to said Fig. 2, the numeral 19 denotes a spindle-body provided with the usual knuckle-joint and an angularly pro- 'ing as bearings for the spindle-bolt. outer ends of sa1d bushings are faced by jecting spindle to receive the hub of a wheel.

7 The body 19 has a longitudinal hollow or bore 20, and in bothends of said hollow are seated the flanged bushings 21 and 22, of like shape, usually made of brass, and serv- The 16 is interposed upon said shaft 1 between i the lower end of the lower bushing 21 or 22 and-the bearing end of the body 5 with said tongue 2-4: in engagementwlth the key seat 23 on the shaft 1, to insure that socket 7 of -the bodyr5 rotates with the shaft 1 it is rotated. The tool is operated for facing the spindle body bushings 21 and 22 by rotating it manually or otherwise, while the cutter head 8 isforced against the'bushing face by means of pressure exerted by tightening body 5 on the threaded end 4.- of the shaft 1. The tongued washer 6 prerents the body 5 from bearing directly against the face of the bushing 21 or 22 and the consequent stoppage of its rotation with the shaft 1,

which would resultin excessive feed and gouging of the cutting blade 13' into the bushing face. By means of the tongued washer 16, the body 5 rotates with the shaft 1, and a fine or coarse cut may be taken at will, depending upon how tightly the body 5 is forced against the washer 16. It is apparent that other constructions may be used in place of the tongued washer 16, to bring about the aforesaid results, and it is my purpose not to limit my invention to this single. construction, but to cover other means of achieving such aresult, as by means of squared or flatted inside edge of washer, or r the rotation with the other means, to insure shaft 1. v 7

Having descrlbed my invention, what I claim as new and desire to secure by Letters Patent, is: a

A facing-tool, comprising a rotatable shaft having one end threaded with a longitudinal key-way in saidthreadedpart, a reversible bit secured removably and longitudinally adjustably upon said shaft, a washer removably and'sli'di'ngl-y mounted upon said shaft" and having a key-projection extending into said key-seat, and a' socket-nut having-one end exteriorly threaded, the socket thereof fitting the threaded end ofsaid shaft; the exteriorly threaded end of the socket-nut when reyersed being adapted to fitthe interiorly-threaded hole of a supportingbody in alinement with and adjustably supporting the abutting end of said shaft to hold thebit' thereon in adjusted engagement with the object to be faced.
